Waves in a Solid Practical

This experiment investigates wave behavior in strings, complementing the waves in a solid required practical curriculum requirements.

Definition: Standing waves form when waves reflect and interfere in a string under tension.

Example: Using a frequency generator to create vibrations in a taut string.

Highlight: The relationship between frequency and wavelength demonstrates inverse proportionality.

Vocabulary: Node - Points in a standing wave where there is no displacement.

Surfaces and Radiation Investigation

This practical examines how different surfaces interact with infrared radiation, crucial for understanding heat transfer.

Definition: Infrared radiation is electromagnetic radiation that transfers heat energy.

Example: Comparing heat absorption and emission rates between matt black and shiny surfaces.

Highlight: Matt black surfaces are both better absorbers and emitters of radiation.

Vocabulary: Emit - To give off or release energy in the form of radiation.
